This is troubling:
Carnegie Mellon University, whose team placed first at Urban Challenge, is partnering up with tractor-maker Caterpillar to build the world’s largest ground robot: a 700-ton robo dump truck capable of hauling 240 tons of earth.
Isn’t this always the way? If somebody can build a 700 ton robot, or a monkey-cyborg, they just go ahead and do it, without ever thinking about where that 700 ton robot is going to drop those 240 tons of earth, or where that monkey-cyborg is going to try to fling its poo.
This is a civilization laying the foundations of its own destruction, very possibly at the robotic hands of 700 ton monkey-cyborgs.
